Now all we need is for this program to be able to understand linker-map.gnu,
so it can avoid trying to demangle C function names.  :-)

I get similar results but in a different order; I don't think that's
significant.  Also I don't get the pthread* symbols, for now I'll just
assume that this particular .so is not from an --enable-threads build.
